Test Data Analysis ToolA new kid on the block
Where are we talking about?
• Every device needs to be tested▶ Consider an airbag with a chip to detect a crash▶ You don’t want the airbag to blowup in your face just
when tapping the dashboard▶ Need to test if the detector operates within limits
• Testers collect data▶ During wafer test and final test▶ This results in data files that need to be analyzed
• Questions to be answered▶ Does the device operate within spec (limits, spread)▶ Does the tester work within spec (dirty needles, sites
equal, contact)▶ Is my process stable over time (Cpk)▶ Is my process repeatable/reproducable (GRR)

Some use cases
• Test environment dependencies▶ Asses site-to-site variation▶ GR&R analysis
• Production well within limits▶ Cp/Cpk analysis
• An analysis tool should provide▶ Clear visualization of problems▶ As little work as possible to assess the test data

Common Workflow at Salland
1. Test 1 part n times▶ Check repeatability
2. Test different setups▶ Test n parts 2 times at system1▶ Test n parts 2 times at system2 ▶ Check repeatability and reproducibility using GR&R
To support this flow DPlus offers▶ Repeatability table▶ GRR table

Why a new tool?
• We want features needed by engineers• We want it to be intuitive and simple• We want a modern look & feel• We want a fast tool that can handle a lot of data
• What we want = what our customers want
